Air supply device

An air supply device, comprising a housing with a cavity being formed therein, the air supply device further comprising:

• a partition plate, dividing the cavity of the housing into an upper cavity and a lower cavity, a first air inlet that is communicated with the upper cavity being formed in the housing, and a static pressure device being arranged in the upper cavity;
• an adjustable baffle plate, having a vertical height less than a vertical height of the lower cavity, wherein the adjustable baffle plate divides the lower cavity into an induction cavity and a heat exchange cavity;
• the adjustable baffle plate and a top of the lower cavity form a first induced air opening;
• a heat exchanger is arranged in the heat exchange cavity;
• a second air inlet that is communicated with the heat exchange cavity is formed in the housing;
• a first air outlet is formed in one side, away from the upper cavity, of the induction cavity;
• and an air vent that is communicated with the upper cavity and the induction cavity is formed in the partition plate;
• wherein the adjustable baffle plate comprises a fixed plate and a moving plate;
• the moving plate is arranged at a position, adjacent to the top of the lower cavity, of the fixed plate in a sliding manner;
• and the fixed plate is connected to a bottom of the lower cavity;
• wherein the air supply device is arranged on an vertical wall with the induction cavity adjacent to the vertical wall;
• a plurality of rotary shutters are arranged on the first air outlet;
• a rotating angle of each of the plurality of rotary shutters is 00 to 90°;
• and a rotating direction of each of the plurality of rotating shutters is away from the heat exchange cavity.
